Hey Electricpete, thanks a lot for your effort.
Unfortunately r has nothing to do with a spatial coordinate thus x can never be equal to r.
r is a degree of conversion (a way to measure how reactants turn into products for chemistry) and dr/dt is a kind of velocity for the conversion, that is...
It is exactly as VisiGoth has written. I am so sorry about the misunderstanding in notation but i usually use an equation editor and not a plain text window for posting....i am really sorry!!
Eq (1) is the general form of the heat equation thus there is no term concerning the first partial of...
Thank you electricpete for your ideas!!
r is the reaction rate and in principle depends on the temperature and time although it would as well depend on the position of the front wave (x). But lets make the problem easier and forget the dependence on x of r...The thing is that to solve eq (1) i...
Thank you VisiGoth for your reply. Indeed i did not want give details about the problem i need to solve as i was not sure of the importance of the post for all you guys.
In my case, i want to model the temperature profile of a combustion wave in combustion of solid fuels. For this reason, i have...
Hi everybody,
Well actually i am not sure of getting an answer from you, as i read a former post you are not about helping MATLAB beginners....any way, maybe someone finds interesting enough my problem.
I have 2 coupled PDEs and i have no idea how to find a solution. I have checked a lot of...
